About this study

Investigators evaluate the gastric volume through cross sectional area and amount of clear fluid using Perlas grade by ultrasound in the supine and right lateral position of fasted patients undergoing cholecystectomy. Full stomach is regarded if solid gastric contents are detected or clear fluid is more than 1.5 ml/kg. The frequency of full stomach will be analyzed.

Inclusion criteria

  • Patients scheduled for cholecystectomy

Exclusion criteria

  • Presence of gastric anatomic abnormality or pathology
  • A previous surgery of esophagus or stomach
  • Current pregnancy
  • Who could not lie in the right lateral decubitus (RLD) position

Treatment and study plan

Ultrasound assessment of gastric contet

Other

Ultrasound assessment of gastric content is performed in fasted patient undergoing cholecystectomy.

Primary outcomes

  1. Incidence of full stomach

    Time frame: Before the induction of anesthesia

    The incidence of full stomach is assessed by using ultrasonography.

Secondary outcomes

  1. Cross sectional area of the stomach

    Time frame: Before the induction of anesthesia

    The cross sectional area of the stomach is assessed by using ultrasonography in the supine and right lateral positions.

  2. Volume of stomach

    Time frame: Before the induction of anesthesia

    The volume of stomach is assessed using the following formula; volume of stomach (mL) = 27.0 + 14.6 x cross-sectional area (right lateral position) - 1.28 x age.

  3. Type of gastric contents

    Time frame: Before the induction of anesthesia

    The type of gastric contents is assessed using ultrasonography.
